Electron transport chain and chemiosmosis: building a proton gradient to produce ATP.
- -The final electron acceptor is oxygen, to make water at the end of the electron transport chain
- -H+ ions (protons) are taken from the matrix and passed onto the other side of the membrane
- -Protons cannot cross the membrane directly, because they are charged
- -As ATP is produced as a result of oxidation of electron carriers, this modeof ATP production is known as oxidative phosphorylation.
